Problems solved by technology

[0003] At present, the qualitative identification of liquor is mainly sensory tasting identification, which requires a certain degree of professionalism; quantitative identification mainly relies on conventional detection methods such as chromatography and spectroscopy, and detection techniques mainly rely on large-scale instruments such as gas chromatography, liquid chromatography, and mass spectrometry. Quantitative identification of liquor can be carried out, but large-scale instruments are required, the capital cost is high, and it is difficult to achieve rapid identification; moreover, the number of people who can be identified is limited to researchers, and it is difficult for ordinary consumers to identify

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0032] The invention provides a method for identifying the quality of liquor. The liquor to be identified is irradiated with the light emitted by a wine appraising pen, and the quality of the liquor is determined through the brightness and color of the Tyndall phenomenon in the liquor. When light of a specific band passes through liquor, the microscopic particles of different liquor colloids are different, and the degree of light scattering is different, so the brightness and color rendering of the light...

Abstract

The invention provides a method for identifying the quality of white spirit. The method comprises the following steps: pouring white spirit to be identified into a colorless transparent container; irradiating the white spirit to be identified by using a white spirit identifying pen; observing the color development of a light path in the white spirit to be identified; determining the quality of the white spirit. According to the white spirit quality identification method provided by the invention, identification can be realized only by utilizing the white spirit identification pen, the detection mode is convenient and easy to operate, and the white spirit quality can be rapidly identified.

Description

technical field [0001] The invention relates to the technical field of liquor identification, in particular to a method for identifying the quality of liquor. Background technique [0002] Wine culture has a long history in China. Since ancient times, my country has a history of drinking liquor, and liquor also occupies a certain share in my country's consumer market. There are many varieties of liquor, and the quality of liquor of different varieties is also different. For liquor of different varieties, how to identify becomes a problem. [0003] At present, the qualitative identification of liquor is mainly sensory tasting identification, which requires a certain degree of professionalism; quantitative identification mainly relies on conventional detection methods such as chromatography and spectroscopy, and detection techniques mainly rely on large-scale instruments such as gas chromatography, liquid chromatography, and mass spectrometry. Quantitative identification of l...
